基于弱测量和量子反弱测量的三能级量子系统稳定研究

摘要

利用弱测量和量子反弱测量方法研究了一个V-型三能级量子系统处在振幅耗散退相干环境作用下的问题。得到了相应的最优化条件、保真度以及成功率解析表达式。通过数值模拟，发现到当弱测量和量子反弱测量强度在满足一定条件下，该退相干的三能级量子系统能有效稳定。%By using the weak measurement and quantum measurement reversal method, we study the stabilization of a V-type three level quantum systems under the action of amplitude of dissipative decoherence. We get the analytic expressions of optimization conditions, fidelity and success rate. Through numerical simulation, we also find that when the strength of the weak measurement and quantum reversal measurement to meet certain conditions, the decoherence of the three level of quantum system could get effective and stable.
